摘要:

为解决临界模式(Boundary Conduction Mode,BCM)单级有源功率因数校正 (Active Power Factor Correction,APFC)反激变换器在全电压输入和可变负载条件下功率因数 (Power Factor,PF)值不稳定甚至严重下降的问题,本文在分析电压型BCM单级APFC反激变换器的环路基础上,提出可稳定PF值的反馈补偿网络,并通过一台30 W的电压型BCM单级APFC恒压输出反激变换器实验样机进行验证.实验结果验证了本文设计的反馈补偿网络的有效性.

Abstract:

In order to solve the problem of BCM (boundary conduction mode) of single stage APFC (active power factor correction) flyback converter PF (power factor) that is not stable or even declines seriously under full voltage and variable load, a feedback compensation network is proposed to effectively stabilize PF, based on the analysis of the loop of voltage-mode BCM single-stage APFC flyback converter. Through a 30W voltage-mode BCM single-stage APFC flyback converter experimental prototype. The experimental results verify the validity of the feedback compensation network designed.

Key words: loop design; full voltage; variable load; boundary conduction mode(BCM); active power factor correction(APFC); flyback
